In the last decade, high-performance Cu 2 Se thermoelectric materials and devices are
attracting increasing research interest. In this review, we firstly summarize fundamentals of …

High-performance liquid-like thermoelectrics have attracted global renewed attention since
the paradigm of 'phonon-liquid electron-crystal'was proposed in 2012. As one of the most …

The atomic‐scale structure of cuprous selenide room temperature phase (α‐Cu2Se), which
plays an important role in understanding the mechanism of its high thermoelectric …

Cu2Se is a p-type semiconducting compound that possesses excellent thermoelectric
properties but degrades at elevated temperatures under large currents, precluding it from …

Chalcogenides have attracted great interest over the last years due to their thermal,
electrical and optical properties. Investigation of the crystal structures of chalcogenides is an …

The structures of the antifluorite-type copper chalcogenides Cu 2 Se and Cu 1.8 S were
studied using single crystal X-ray diffraction data both below and above the transition point …

Super-ionic solids, which exhibit ion mobilities as high as those in liquids or molten salts,
have been employed as solid-state electrolytes in batteries, improved thermoelectrics and …

Finding alternatives for Bi2Te3, the only thermoelectric material for near-room-temperature
(RT) applications, is of great importance in thermoelectrics. Here, we report a very promising …

Recently, many novel superionic thermoelectric materials have been discovered along the
concept of “phonon-liquid electron-crystal”(PLEC). Among them, Cu 2-x Se-based liquid-like …

The crystal structure uniquely imparts the specific properties of a material, and thus provides
the starting point for any quantitative understanding of thermoelectric properties. Cu2− xSe …
